OK i'm getting interested in long range shooting and varmiting and i don't really know where to start. i'm looking at a starter gun that i can turn into a 1000yd match gun. i was looking at the Remington SPS varmint and thought that would be a good starter, but if there is any others i would like to know them as well. i'm on a smaller budget, so i can't spend thousands of dollars at once. also i need to find out what caliber would be the best. i was thinking about the 243 sense alot of guys use other 6mm rounds. any help on this issue would be great. thanks
